The apparatus embodying this invention may be advantageously used,wherever dialare used, with substantialis'aving in time and labor andwith the elimination of possible errors in dialing, and will be ioundparticularly advatageous for subscribers as banks, brokerage houses andthe like whose business require them or their priVate-branch-exchangeoperators to make a large number of daily calls in succession or'inrepeated succession.

Referring to Fig. 1, an ordinary telephone of the dial-operated typeusually employed at subscriber-stations is shown, and comprises atelephone 1, a receiver 2, a receiver hook 4 and a finger-wheel 5 formanual transmittal of telephone numbers; The telephone 1 is adapted tobe fixedly held to a base 6 by means of a plurality of brackets 7engaging the lower sides of the telephone base 9. As shown in Fig. 2,one of these brackets is movable and adapted to be operated by anysuitable means, to provide for the positioning an removal, wheneverdesired, of the telephone 1 on and fromthe base 6 respectively.

Referring particularly to Figs. 1 and.-7,

the base 6 has fixed thereto a motor 11, the

' shaft of which carries a worm 12. Also secured to the base 1 is 'afame 14 carryinga stud 15 around whicha gear 16 engaging with the worm12 is adapted to rotate. A magnetic element 17, preferably in the formof a disc,

is adapted to rotate tive to said-disc. Said clutch 20 may be car-.around the shaft 32 and 41-.(Fig. 7) sitioned and which may beformeddntegral with the gear 16. The stud 15 alsoprovides a pivot for agear 19 19'as to move with Thus, when the clutch with said gear 27. Abevel gear 30 is adapted to rotate with the gear 29 and may be madeintegral with the latter so as to rotate around the pivot 25. Meshingwith the bevel gear 30 is another bevel gear arounda rotatable shaft 32,the bearings and SXEPPOItS of which will be described hereina ter.

Referring to Figs. 3 and 3a, the shaft 32 carries a pin 3 1 whichextends through a slot 35 formed through a hub 36 movably fitted' whichmaybe integra with the bevel gear 31 so as to rotate with the latter.Carried by the hub 36 is a pin 37 and a tensibn spring 39 has its endsconnected to pins 34: and 37 respectively. The pin 34 serves to maintainthe bevel gear 31 in engagement with the bevel gear 30, and, incooperation with the pin 37 and the spring 39, to provide rotation-oftheshaft 32 by reason of a rotation of the bevel gear 31'. The pin 34 andthe slot 35 serve, however, an additional purpose which will beunderstood in the later description. Fixed to the shaft 32, near one endthereof, is a rotatable element or I cam 40 having a series of steps orprojections which are predeterminedly potherewith.

From the above apparent that arotation of the gear 19, by reason of theaction of the clutch 20 on the re volving disc 17, causes acorresponding rotation of the element iO through the medium of thepinion 26, the gears 27 and 29, gears 30'and 31 and the-shaft 32.

In accordance with the invention, the element 40 is caused torotatesuccessivelyfrom a normal position of rest, and abutments 42predeterminedly formed ou -telephone number records 44, (see Fig. 14),are caused to successively cooperate with projections 41 of the element40 in limiting the successive rotations of, the element 40, wherebydefinite arcuate movements are imparted to the element 40; and movablemeans are provided for imparting to the impulse transmitting device 5"movements corresponding to said suc- 31 movably fitted as Idescription, itnow becomes the bevel cessive mo'veinents of theelement40. In the gears 19 and 27iandzterminating with a fin-L (which, it isnoted, are caused to rotate in the same direction by reason of thepinion 26 meshing therebetweenl by means of the studs 47 and 49eccentrically secured to the gears 19 and 27, so that arcuate motionsare imparted to the finger 46 for actuation of the device 5 whenever thegears 19 and 27 and the element 40 are rotated. The rotatable element 40and the movable means in liaison therewith are retained in a normalposition of rest by any suitable means, such as a projection 49, (Fig.7), formed on the element 40 and cooperating with a fixed abutment 50and with a helical spring 52 (Fig. 1), coiled around the stud 24. oneend of which spring may be fixed to the lower surface of the gear 27 andthe other end of which may be fixed to the frame 14. Said abutment 50 ispreferably formed 'on a magazine structure 51 which will be describedhereinafter. Said spring 52 also serves to restore the element 40 andthe movable means including the link to their normal position of restafter each successive movement of same.

The projections 41 on the element 40 are necessarily equal in number tothe number of the usual finger-wheel openings 54. (usually ten) Theseprojections 41 are so positioned relatively to one another and to theprojection with the finger 46 preferably enga ing the advance of thedevice 5 from the finger-catch 53. actuations of the device 5,corresponding to definite movements of the element 40 governed by saidprojections 41 co-acting with telephone number record abutments 42predeterminedly placed inltheir path, result in .proper transmittal oftelephone numbers.

Means are preferably provided formaintaining the finger 46 out ofengagement with the device 5 when said finger is in its position ofrest. In the embodiment of the invention shown in the drawings. thesemeans comprise a pivotal connection 55 of the finger\46 to the main bodyof the link 45 and a supporting post 56, fixed to the frame 6. Said post56 has its upper end formed with an inclined surface over which thefinger 46 is adapted to move, whereby the finger 46 is raised out ofengagement with the device 5 when it is restored to its normal positionof rest. and lowered in operative engagement with the device 5 when itis rotated from its position of rest. A projection 57 fixed to thefinger 46 cooperates with the link 45 in limiting he downward movementof the finger 47 for proner cooperative action with the device 5. hespring (not shown) usually associated with a finger-wheel for restoringthe latter to its position of rest assists the function of the spring49. which governs their positions ,of rest, that,

52 in restoring the-element '40 and the movable means including the link45 to their normal position of rest.

It is to be noted that the lowering and raising of the finger 46 in andout of engagement with the device 5 necessitates an initial movement ofthe finger 46 before engagement of the latter with the edge of theopening 54, successive movements of the finger 46 for actuation of thedevice 5 being thus necessarily greater than the movements of the latterby this initial movement of the finger 46. These required greatermovements of the finger 46 are provided by suitably positioning theprojections 41 with relation to the projection 49 -which governs theposition of rest of the element 40. A relative disposition of theprojections 41 and of the projection 49 on the element 40, suitable forproper operation of a finger-wheel 5 of the usual type provided intelephone apparatus; is shown in Fig. 7.

One of the edges of the projection 49 cooper-' ates with the abutment 50in determining the position of rest of the element 40, but the oppositeedge of said projection 49 serves as a projection 41 to produce, incooperation with a telephone number record abutment 42, the greatestarcuate movement of the element 40 for transmittal of an electricalimpulse by the finger-wheel 5.

The clutch 20, cooperating with the revolving disc 17, is caused tobeenergized and de-en'ergized, re pectively, at substantially the instantthe element 40 reaches its position of rest and at substantially theinstant such element cooperates with an abutment .42. Referringparticularly to Fig. 3, two spring contacts 59 and 60 providingswitching means for the magnetic clutch 20 are adapted to be heldnormally in contact with one another, and, when in this normal positionofcontact. permits a current to flow through .the clutch'20. Saidcontacts 59 and 60 are carried by an insulating block 61, which may besecured to the magazine structure 51, and

may be provided with terminals 59a and 60a for connection thereto oflead-in wires. The shaft 32, rotatably mounted at one end in asupporting bracket 62 which may be secured to said structure 51, has aninner bore in which is slidingly fitted a plunger 64, to the outerprojecting end of which is secured an insulating cap 65 co-operatingwith the spring contact 59 in opening and closing the spring contacts 59and 60. A compression 64. Saidpin 70 cooperates with a projecment 42 isplaced in the path of a projection 41 of the element 40, the rotation ofsaid element-and of the shaft 32 fixed thereto is instantaneouslyarrested, although the train of gears 19, 26, 27, 29, and 31 may stillcontinue rotating by reason of the yieldable connection of the gear 31with the shaft 32, the pin 34 being relatively displaced in the slot 35against the tension of the spring 39. The gear 31, upon rotation withrespect to the shaft 32, causes the pin 70 to cooperate with the cam 71,so that an outward movement of the plunger 64 and a correspondingseparation of the springs 59 and 60 is produced, this de-energizing theclutch 2O whereupon rotation of the gear 31 and its associated train isdiscontinued. The cam 71 is formed with a catch 72 which retains the pin70 in an outward position against the force of the spring 39, thispermitting a continued separation of the springs 59 and 60 andcorrespondingly permitting the element 40 and the movable means inliaison therewith to reverse in rotation and be restored to their normalpositions of rest by reason of the action of the spring 52. It is notedthat, when the reverse rotation of the element 40 is checked by thecooperative action of the projection 49 on said element with theabutment 50 (Fig. 7), the reverse rotation of the shaft 32 and of thepin 34 is also arrested,

buta continued rotationof the train of gears I including the bevel gear31 is caused by'the action of the springs 52 and 39, effecting a(reverse relative displacement of the pin 34 in the slot 35 and arelease of the pin from the catch 72 and cam 71. The plunger 64 is thenretracted by the spring 66-and the springs59 and 60 close to againenergize the clutch 20. Evidently the normal position of rest of all ofthe gears described is determined by the pin 34 co-actin'g with oneendof the slot 35, as shown in Figs. 3a and 3b.

. Means for permitting passage of current throu'ghthemevable clutch 20comprise a pair ofslip rings 74 and 75 (Figs. 2 and 12), carried by aninsulating element-secured to the gear 19 on its uppersurface. Said sliprings 74 and 75 may be provided with terminals 74a and 7 5arespectively. Conductors '76 and 77 connect the terminals of the clutch20 to the slip ring terminals 79a and 79b reepective'ly, said conductors76 and 77 rotatin with the gear 19 and the clutch 20. An insulatingplate 82 (Fig. 2) holds a pair of brushes 80 and 81 in operativeengagement with the slip rings 74 and 75 respectively. Said plate 82 maybe conveniently secured to 85 the post 56. Terminals 80a and 81a for thebrushes 80 and 81 respectively permit connection of'lead-in wires 84 and85.

From the above description it becomes apparent that by properenergization and deenergization of the clutch 20, definite suc- Icessive movements from a position of rest may be automatically impartedto the finger 46. It is noted that these movements are not in exactidentical proportion to the movements of the element 40 by reason of thedisplacements of the gears 19.to 31 and of v tioned to properly actuatethe device 5 for transmittal of telephone numbers, when definite arcuatemovements are imparted to the element 40.

In accordance with the invention, means are provided for displacing atelephone number record 44 the distance of an abutment 42 for eachsuccessive rotation of the element 40, so

as to provide successive rotation limiting acs I tions of abutments 42with cooperative proj ections 41. Referring particularly to Fig. 1, themagazine structure 51, which will be later completely described, has anopen slot 83 within which the projections 41 of the element 40 arenormally free to rotate and the inner end of which forms the aforesaidabutinent '50. co-acting. with the projection 49 on the element 40 inlimiting reverse rotations of the latter. v 4 I Said structure 51 socarries a telephone number record .44 as to permit the aliutments 42 ofsaid record to be successively positioned within the slot 83 in the pathof projections 41 for cooperation therewith, when said record iscau'sed'to be displaced. Said structure51 is carried tively to one sideof the structure 51 and to the base 6. A carriage 87, preferably in theform of an elongated flat strip, has bifurcated ends 87a and 87bslidingly held within corresponding slots89a and 896 (Fig. 4) formedthrough the side of the structure 51', and is also slidingly held by aclamp 90 secured to by a flat angu- I lar bracket 86 having legs securedrespec the supporting bracket86. The ends 87 a and 87 b of the carriage87 when the carriage 87 is caused to move, cooperate with a long edge ofa telephonenumber record 44, assumed to be initially operativelypositioned in the structure 51, in displacing said record in thestructure 51. v

A spring 91, one end of which may be se- .125,

cured to a projection 92 integral with the. carriage 87 andthe other endof which may be secured to a side bracket 93 fixedto or integral withthe bracket 86, cooperates with a pin 94 co-acting with the carriage 87in re taining the latter in a normal position of rest,

the ends 870 and 87 b of the carriage 87 bein then still retained withinthe slots 89a an 89?). Secured to the carriage 87 is a ratchet 95 whichcooperates with a pair of pawls 96 and 97 in displacing the carriage 87and correspondingly displacing abutments 42 within the slot 83 in thepath of projections 41. The pawl 96 serves to retain the carriage 87against the force of the spring 91 when said carriage 87has beendisplaced by the pawl 97 by means which will be presently described. Thepawl 96 may be pivotally carried by the bracket 86 and is normallyheldin operative engagement with the ratchet 95 by means of a spring 99which may be secured at its ends to the pawl 96 and to the clamp 90respectively. The mechanism actuating the pawl 97 comprises a lever 100ivotally connected between its ends to a fixe stud 101, which is securedto a support 102. The latter may provide a beari \g for the shaft 32 andmay be made integral with the stud 25 secured to the frame 14. One endof the lever 100 is pivotally connected to the pawl 97, and its otherend 103 cooperates with a recess 104 formed on the upper surface of awheel 105 which may be secured to or made integral with the gears 29 and30, so as to rotate with the latter. A spring 107 having its endssecured respectively to the pawl 97 and to the lever 100 normallyretains the pawl 97 in operative engagement with the ratchet 95. Whenthe element 40 and the movable means in liaison therewith including thewheel 105 are in their normal position of rest, end 103 of the lever 100normally rests in the recess 104; but, when said element and wheel arecaused to rotate, said end 103 is caused to slide out of there'cess.104, this causing an arcuate movement of the lever 100 and permittingthe latter in cooperation with the pawl 97 to adlac'd osition. P B PVance the ratchet 95 and the carriage 87 against the force of the spring91, thereby advancing the telephone number record 44 the distance of anabutment 42 in the structure 51 and placing an abutment 42-within theslot 83. When said element and wheel are being restored to theirposition of rest, the lever. end 103 slides back into the recess 104,thus restoring the pawl 97 to its original position but advancing samealong the ratchet95 by reasonof 'the action of the other pawl 96 whichhas retained the ratchet 95' in its dis- Thus the lever 100 and the pawl97 may again advance the ratchet 95 and the carriage 87 when saidelement 40 and movable-means are again rotated. It is noted that theaction of the lever end "103 with the I recess 104 is such that thecarriage 87 is abutment 42 being thus quickly displacedinto the slot 83so as to place said abutment in.

quickly displaced the moment the element 40 starts rotating, a telephonenumber record operative position for cooperative'action with aforthcoming cooperative projection 41 of parted to the element 40 forproper automatic actuation .of the device 5.

In accordance with the invention, means are provided for automaticallyreleasing the carriage 87 to itsnormal position of rest after completionof successive cooperative actions of projections 41 with abutments 42 ofa telephone number record 44. Also, means in cooperation with the usualswitch or ,receiver hook 4, rendering the telephone operative andinoperative to start andend a call, are provided for automaticallyrendering operative the motor 11 and the clutch 20, which cause thevarious movements of the apparatus described. Still othermeans areprovided for automatically rendering inoperative said motor 11 andclutch 20 after the device 5 has been actuated for proper transmittal ofa telephone number.

Referring particularly to Fig. 1, the shaft 32 has an end projectingoutwardlyifrom the aforesaid bracket 93 to which it is rotatablymounted, this end being fitted with a collar ios end of which may beconnected to the bell crank 111 and the other end to the bracket 86cooperates with a pin 119, fixed to the bracket 86, in retaining thebell crank '111 in a nor mal position of rest, thereby permittingengagement of the pawls 96 and 97 with the ratchet 95. A pin 120 ispredeterminedly secured to the outermost end of the carrage 87 so thatthe last,

displacement of. the carriage 87, caused by the last rotation of theelement 40, causes said pin to cooperate with arm 1116 of the bell crank111 in forcing the inclined surface 121,-formed on'the end of. said arm1116, in

the path bf the'pin 110, thereby causing a swinging action of thebell-crank 111 against the force of the spring 117 and at raising of thepawls 96 and 97 by the catch 114 out of operative engagement with theratchet 95. When this action occurs, the carriage 87 is substantiallyinstantaneously restored to its normal position of rest by reason of theaction of the spring 91. A

ICC

- an the pin 110 to reverse in rotation and be It is noted that theoperation of the bell crank 111 depends on a rotation of the element 40.For a purpose which will be later understood, the operation of the bellcrank 111 is caused by a rotation of the element 40 produced after allof the abutments 42 of a telephone number record have co-acted with theelement 40. This after-employed rotation of the element 40 is made smallso that the corresponding movement of the device 5 by the finger 46 doesnot result in a transmittal of an electrical impulse. It is noted that adevice 5 of the type shown in the drawings must be actuated over anappreciable arcuate length, before an electrical impulse may betransmitted by same, so that proper transmittal of telephone numbers isnot impaired by the last movement of the device 5 caused by saidafter-emplo ed rotation of the element 40. -As will be aterunderstood,'saidafter-employed short rotation of the element 40 ischecked by a de-energiza .'tion of the clutch 20, caused by the means,

, i the pin 110 ocbu'rs,the end 121 of the bell crank" which are to bedescribed, for automatically rendering the motor 11 and the clutch 20inoperative after a transmittal of a telephone number.

Thus, the checking of this final rotation of the element by ade-energization of the ma etic clutch 20 permits the element 40 restoredby the spring 52 to their normal position of rest. r When this reverserotation of 111 moves out of engagement with the pin ,a 110, therebycausing a lowerin of the catch 114 by reason of the'action of t e spring117. ,The pawls 96 and 97 are then lowered, by

Qwith'a telephone number record for a sucreason of the action of thesprings 99 and 107, in operative en agement withthe ratchet 95 in itsosition 0 rest so that the carriage 87 may e again displaced forcooperation ceeding automatic operation of the device 5.

Referring particularly to Figs. 4 and 5,

the means for rendering the power means including the motor 11 and theclutch 20, controlling the various movements of the apparatus described,automatically operative and inoperative, comprise two switches 134 and135 both of which control said power means. One switch 134 isautomatically closed and opened upon actuation of the switch or receiverhook 4 to start and end a call, respec-' tively. The other switch '135is automatical- 1y closed when actuating the receiver hook 4 to end acall, and is automaticall opened after the various movements of t e aparatus to automatically transmit a telep one number, including therelease of the carriage 87, have taken place.

A vertical rod 136 (,Fig. 1) having its upper end formed with a clasp137, engaging thereceiver hook 4 so as to move the same, slidinglyengages a tubular support 139, se-

surface of the base 6. Fixedly secured to the shaft 141, at apredetermined point, 'is another crank 144, (Fig. 7), the outer end ofwhich is pivotally connected to 'a vertical rod 145 extending throughthe base 6. The

upper end of the rod 145 is pivot'ally connected to a link 146,pivotally mounted on the structure 51 by the pin 147 fixed to one sideof said structure, said pin 147 permittin an arcuate motion of the link146. Said ink 146 carries an insulating block 149 to which a contactpoint 153 cooperating with the spring contact 150 in providing the owercontrol switch 134. Said contact 153 is also provided with a terminal154, said contact 153 and terminal 154 being insulated from the bracket152 by any suitable means.

The upper end portion of the tubular support '139 is formed with aninner bore 155 of diameter suitably greater than that of the rod 136. Acompression spring 156 is positioned in said bore 155 between acollar-157 fixed to the rod 136 and the shoulder 158 formed by the lowerend of the bore 155. This spring 156 serves to move the rod 136 upwardlywhen the receiver 2 is removed from the receiver hook 4, the rod 136beingmoved downwardly, by reason of the weight of the receiver 2,against the force of the spring 156, when the receiver 2 is a ain placedin position on the receiver hoo 4. It is noted that the springarrangement, (not shown), usually associated with a receiver hook 4,assists the function of the spring 156 in raising the rod 136 when thereceiver 2 is removed from the receiver hook 4. It is now readily seenthat a removal of the receiver 2 from its support 4 causes an upwardmovement of the rod 145 and of the link 146, thereby automaticallyclosing the contacts 15(Land 153. The latter are adapted to control boththe operation of the motor 11 and of the magnetic clutch 20, so that,when a telephone record 44 is properly positioned in the strucoperateswith a movable contact 160, which may be provided with a terminal 160a.Said contact 160 and terminal 160a are secured to an insulating block161 carried by an arouately movable member 162, the latter ,to-

gether with the,contacts 159 and 160 forming the power control switch135. The member 162 is pivotally mounted on a stud 164 fixed to thebracket 86. The contacts 159 and 160 are frictionally held in engagementwith each other against the force of a tension spring 165 one end ofwhich may be connected to the member '162 and the other end to thebracket 86, this holding engagement being insured by providing a recess163 on the contact 160 into which recess the curved end of the contactspring 159 is adapted to enter as shown in Fig. 4.

A right-angle foot 166, fixed to or integral with the arm 111a of thebell crank 111 at one end thereof, projects through a slot 167 formedthrough the bracket 86. This 'foot 166 raises the member 162, therebycausing a disengagement of the contacts 159 and 160,

when the arm 111a is caused to be raised by the action of the pin 110with the .inclined surface 121 of the bell crank 111, said spring 165then functioning to retain the member 162 in raised position. Evidently,the disengagement of the contacts 159 and 160 deenergizes the clutch 20and permits the element 40 and rotatable means in liaison therewith tobe restored to their position. of rest. It is readily understood thatthe action of the pin 110 and bell crank 111, which de- 'pends on a lastrotation of the element 40,

is to first release thecarriage 87 to 'its position of 'rest, and thenopen the contacts 159 and 160, thereby limiting this last rotation ofthe element- 40. By proper design of the pin 110 and inclined surface121 cooperating therewith, the opening of the contacts 159 and 160 andcorresponding d-energization of the clutch 20 are caused to occur afteronly a short rotation of the element 40. The movement of the device 5corresponding to this last short rotation of the element 40is .thus alsosmall and less in magnitude than that definite movement which the device5 requires before it may transmit anelectrical impulse, so that propertransmittal of a telephone number is not affected by this last rotationofthe element 40. It is noted that.

the ratchet 95 and carriage -87' are displaced, by reasonof the quickaction of the lever 100 with the wheel 105, before the action ofthe pm110 with the-bell crank 111 takes place, this last displacement of thecarriage :87 being useful for a purpose which will be. understood in thelater description.

' Referring particularly .to Figs. 4 and 5, the' link 146 carries a foot169 which lowers the switch member 162 from a raised tion, therebycausing re-engagement o the contacts 159 and 160, when said link 146 ising of either of the switches 134 or-135, when closing of the contacts59 and again by osicaused to be moved downward against the force of thespring 155 by reason of a downward movement of the receiver hook 4, asby a positioning of the receiver 2 thereon upon a completion of a call.Thus, assuming the 7( operative, thereby stopping the movements of theapparatus described, by reason of the opening of the switch 135. Whenthe receiver 2 is again positioned on the receiver hook 4 after theparticular call has been made, the switch 135 is placed automatically ina normally closed position by the foot 169, so that the apparatus isadapted to automatically start functioning when the re-.

-ceiver2 is again removed for making a succeeding call. K

Another power ,control switch 189 '(Fig. 2) serves to render theapparatus inoperative in case itis desired to dial the fingerwheel 5manually, and is conveniently located on the base 6 for manualoperation. Referring to the wiring diagram, shown in Fig. 16, themotor'll is placed in series with the control switches 134 and 135 by aconductor 190, said motor and switches be-' ing electrically connectedto the switch 189 controlling the source of energy 191. One brush 80, inelectricalconnection with a terminal of the clutch 20 through the slipring 74, is electrically connected by a conductor 84 to the conductor190 and thus through the switches 134 and 135 to one side of the switch189. The other brush 81', in electrical connection with the otherterminal of the clutch 20 through the slip ring 75, is connected by aconductor 85 to the spring contact 60. The spring contact 59 cooperatingwith the contact 60, isielectrically connected to the other side of theswitch 189 through a suitable resistance 192.

Thus, when the switch 189 is closed, a closthe other is closed, renders"both the motor 11 and the clutch-20 operative, and an opening of eitherof the switches 134 or 135, when the other is closed, renders both themotor 11 and the clutch 20'inoperative. Also, assuming all threeswitches 189, 134 and 135 to be closed, an opening of thecontacts 59 and60. by action of the plunger 64 de-energizes. the clutch 20, but permitsthe motor 11 to continue revolving, so that, upon reaction of theplunger 64, the rotary movements of the element 40 and of the finger I46act-u'ating the device 5 are substantially r instantaneously started.

In accordance with" the invention means are provided for automaticallyplacing in purpose of calling a plurality of parties one after theother; means are provided for facilitating manual positioning of any ofvsaid telephone number records, out of rotation, in operative positionfor proper co-' operation with the apparatus described.

Referring particularly to Figs. 4, 5, 6, and 7, the structure 51comprises two containers or magazines 170 and 171, rectangular incross-section, and preferably contiguous to one another. The structure51 may be formed as a unit with a vertical partition 172 so positionedas to divide the structure 51 into two compartments forming thecontainers 170 and 171. The latter are made open at the top and closedat the bottom.

A telephone number record 44.is made for each telephone number which itis desired to transmit automatically. Referring to Fig. 14, thesetelephone number records, preferably made of metal, have legs 174 and175 formed at extreme ends of the short edge on which the abutments 42are formed, these legs 174 and 175 permitting the abutments 42 to beproperly spaced with relation to the parts of the apparatus with whichthey function. The records 44 are preferably provided with indications17 3a of the parties and .their telephone numbers, which indications areafiixed to the front faces of said records. If desired, tabs 1731) maybe so positioned respectively on the top edgesof the records 44 thatthey may all be visible when the records 'are placed in stackedrelation, manual removal of any particular record out of the stack beingthus facilitated.

The container 17 0, serves to hold the records 44 in stacked relationwith their legs 174 and 175 resting against the bottom thereof beforeautomatic transmittal of their numbers, and the container 171 serves tostore the records 44 after automatic transmittal of 1 their numbers,-thetabs'173b, if provided,

being visible and permitting easy removal of any of the records from therespective containers. Both containers 170 and 171 have resilient means178 .(Fig. 7), holding the telephone number records in stacked andindexed relation against the front end of the containers. Theseresilient means 178 may each comprise a spring arrangement 17 6, op-

"carriage-87, and is transferred by the carriage 87 from the container170 into the container 171 through a uassage or slot 181 (Fig.-

6), formed in the plane of the carriage 87 by spacing the partition 172from the front end of the structure 51. This transfer effected .bycooperative action of the ends 87a and 87b of the carriage 87 with theadjacent long edge of said foremost record when the carriage is causedto be successively displaced, the abutments 42 of said recordsuccessively passing by the slot 83 formed in the front end of thestructure 51. The front wall of the containers 17 0 and 171 arepreferably provided with openings which expose to View the front face ofthe record to be or being transferred, so as to make known to theoperator the party to be or being called.

. Referring to Fig. 5, the bottom of the container 170 is in a planeabove the plane of the bottom of the container 171, the records in thecontainer 17 O projecting above its open end. The bottom of thecontainer '17 0 (Fig.

7) terminates'a substantial distance from thefront wallof the containerso as to provide a slot 182 which is in the plane of the slot 181 and ofthe carriage 87. The forward end of the bottom of the container 170carries a depending wall 184 which is spaced from the'lower ordepending. portion 184a of the front wall of the container a distanceequal to the width of the slot 182, the walls l84 and 184a beingconnected at their lower ends by a referred to, vis formed by cuttingaway the conti uous walls 184 and 184a of the pocket or su container 188adjacent the partition 172. It is to be noted that the bottom section183 of thesubcontainer is in horizontal alignment with the bottom of thecontainer 171, so as to permit unobstructed passage of the successiveforemost records from the sub-container 188 to the container 171 throughthe slot 181; and it is to be also noted that the successive foremostrecords are prevented by friction from dropping through the 'slot 182.

It n'ow becomes apparent that the successive foremost records inthescontainer 17 0, when lowered into the subcontainer 188, areinitially positioned for proper cooperation with the element 401 as wellas with the carriage 87, in which position the leg 174 of a record islocated within the slot 83.

Assuming the foremost record in the container 0 to be initiallypositioned for proper cooperation with the carriage 87 and with theelement 40, an actuation of the receiver hook4 to start a call. startsthe functioning of the apparatus,-the carriage 87 dis lacing the leg 174of said front record into t e container 171 and displacing its firstabutment 42 into the slot 83.:for cooperation with the first rotation ofthe element 40. Abutments' 42 of said front recgd are then successively'bottom section 183 so as to form a pocket or I a displaced into theslot 83, for-cooperation with the element40,'while said front record issimultaneously being-transferred into the container 171. k

Upon complete transfer of a record by the carriage 87 into thecontainer171, the resilient mechanism 178-in the container 170 acts todisplace the remaining records in the container 170 toward the front endof the latter, this forward displacement ofthe rep maining records onlytaking place after the carriage 87 has-been released to its normalposition of rest. Thus, the resilient mecha nism 178 inthe container 170serves to place the records in said container, one after the other,contiguous to i s front end and in the of the opening of the switch 135.

plane of the carriage 87and slot 182. To-

permit the telephone number records to be .successivelyzstored in thecontainer ,171, a

tainer 171, and is so curved at its free end.

that, by reason of its yielding action, it permits transfer'of arecordbetween it and the preceding records which have been stored.

.. It is noted that a rotation of the element causes a displacement ofan abutment 42 which limits this same rotation of the element. Thus,after all of the abutments 42v sponding to the record which has beenoperativelypositioned by the finger 186 at the end of record havesuccessively limited the ro- 1331310119 of the element 40, the lastabutment 42 is still in the slot 83. Consequently, two further rotationsof the element 40 are needed to cause the carriage 87 to completeldisplace the record from the container 1 0 into the container 171' forstorage in the latter, the first of these two after-employed rotationsof the element displacing the last abutment42 out of the slot 83 and thesecond displacing the leg 175 out of said slot 83.- The first of thesetwo after-employed rotations of the element 40 maybe checked by theaction of a projection 132, (Fig. 7), formed on the tainer 171, ischecked by the demagnetiza-- tion ef the clutch 20, caused by theopening of the switch 135 as has already been explained.

It is noted that this final rotation of the ele- 'ment 40 firstcauses'the final displacement of the carriage 87, then the release ofsaid carria e, and finally the opening of the switch 135. t is evidentthat, by making the leg 175 of a telephone number record of such smallwidth as to be incorporated within the last abutment 42 of said record,only one after-employed rotation of the element 40 is then needed .tostore said record in" the container 171. This single after-employedrotation of the element 40 may be checked by the demagnetization of theclutch 20 by reason Referring particularly to Figs. 1 and 4:, the Q endof the link 146 is formed with a finger 18.6, 'which cooperates with thetop 'edgelof a front record in the container 170, initially held byfriction in its upper position, in lowering said record to the bottom183 of the sub-container 188, when thereceiver hook 4.- is actuated toend a call, thereby initially positioning said record for propercooperation with the apparatus described. Thus, when the receiver hook 4is again lifted to start a call, the apparatus automatically starts todial the telephone number correof the preceding call.

Thus the apparatus cally transmits in succession the telephone numbersof'various parties, for the purpose of calling these parties one afterthe other, p

with the only manual labor involved being the raising and lowering ofthe receiver 2 o and on the receiver hook-4, to start and end eachcall,all of the telephone number records provided for these various partiesbeingsuccessivelyv transferred from the container 170 into the container171 for storage therein.

If it is desired to call a certain party out of -rotation, itscorresponding record-.may be element 40,-on the leg 175 of a record,said leg 175 being positionedin the slot 83 by reason of said firstafter-employedrotation of theelement 40. Said projection 132 isformedprior totheprojections 41 in the directionof advance of the element 40,so that the movement fofthe device 5 causedby thisfirst afteremploy'edrotation of the element 40.i s less than the definite movement requiredfor transmittal of van electrical impulse, proper.

transmittal of telephone numbers being thus 8 unimpaired. The lastafter-employed rotation of the element 40, causing-complete transferofva record for storagein the conmanually removed from eitherv stack ofrecrecord in the container 17 Ois caused manually to slideupwardlyout'of the slot 182, manual pressure is exerted through the frontopening of the container 170 on the stack of records in said containeragainst the force of described automati- 'ordsin the containers 170 and171, the front the resilient device 178, and the removed recordplacedahead of the front record in the contailier 170.

Since the number of required actuation's' of a device" 5 for transmittalof telephone numbers inay vary, means .are provided to adapt the.apparatus for general use with relation to said variation in the numberof required actu-.

ations of the device 5. h

Referring to Fig. 14, the telephone number record shown is formed withseven abutments 42 causing seven transmittals of electrical mittal ofthe particular telephone number corresponding to this record. The widthof the latter, however, is such that its lower edge .may accommodate agreater number of, abutments, say nine. After the abutments 42 of therecord shown have all successively 'co-- operated with the element 40,further rotations of the element 40 are needed to cause the completetransfer of the record into the container'171 due to the presence of theedge portion 187. of the record, non-useful for transmittal ofelectrical impulses by the devioe'5. The edge portion 187 of a recordmay be utilized in limitin said further rotations of'the element 40..Tire edge portion 187, by proper construction of the records 42 and'ofthe apparatus described, may be formed in horizontal alinement with thebottom edges of the legs 174 and 17 5. Thus, the edge portion 187cooperates with the rojection 132 in checking the aforesaid nee edrotations of the element 40 to transfer a record. These rotations of theelement 40 are less in magnitude than the rotation which causes thedevice 5 to transmit an electrical impulse, so that proper transmittalof telephone numbers is not interfered with. When a record, constructedas shown in Fig; 14, is employed, the element successively rotates seventimes to actually transmit the telephone number, then rotates once todisplace t e'last abutment 42 out of the slot 83, then successivelyrotates twice to displace the edge portion 187 out of the slot 83, thenrotates once to displace the leg 175 out of theslot 83 and finally storethe record in the container 171, this final rotation being checked bythe opening of the power control switch 13 From the above description,it is apparent that, by proper design of the apparatus described,telephone numbers requiring difierent numbers of actuations of thedevice 5 for transmittal of electrical impulses, may be automaticallytransmitted without altering an of the parts of said apparatus. A

The afore-- said foot 92, formedon the carriage 87 coopprates with a collar 196, fixed to the typew eel194, inv displacing the latter longitudi- 87 is displaced. Secured'tothe bracket 86, at o posite edges thereof, are'the aforesaid sideracket93 and the side bracket '197, both of said side-brackets being spacedfrom one another and Saar right angle to the bracket 86. These brackets93 and-19 carry fixedbearings 199 and 200' for mounting therein of theshaft 32, the typewheel 194 rotatable ,with, the

- edges being movable partially within the space between said,brackets93 and 197. The bracket 86 is formed with a rectangular opening 201, asbest seen in Fig. 8, so located as to permit proper movement of thetypewheel 194, a portion of which extends through said opening. Thepurpose of this opening 201 will be understood in the later description.It is seen that successive rotations of the element 40 to actuate thedevice 5 impart corresponding rotations to the typewheel 194. The latterhas type figures formed on its periphery, preferably corresponding tothefigures usually associated with the openlngs 54 of a finger wheel 5..These type figures areso positioned that they cooperate with a printingmechanism, actuated at the instant that a projection 41 of the element40 co-acts with an abutment 42 of a telephone I number record 44, inprinting on a record sheet 204 the figures corresponding to thesuccessive actuations of the device 5. 'It is understood that the firstfew printed figures 1 on the record sheet 204 given an indication ofthetelephone ofiices or exchanges to [which the called parties'areconnected, the printed records on the sheet 204 thus giving a coinpleteindication of the telephone numbers automatically transmitted;

In the embodiment of-the invention shown in the drawings, the printedmechanism referredto comprises a hammer 202, (Fig. 2),

operated by a solenoid mechanism 203 (F1g. 9) which is successivelyenergized at the instant that abutting actions of projections 41 of'theelement 40 with abutments 42 of a telephone-number record 44 take place.The paper ribbon 204. is operatively positioned between the-haminer 202and the typewheel 194-, and is fed under tension therebetween in adirection perpendicular to the axis of the shaft 32 from the pa er roll205 (Figs. 1 and 8) to a take-up reel not shown in the drawing) Saidpaper roll 205 is remov'ably carried by a pin, supported parallelly tothe axis of the shaft 32 by brackets 206 and 207. The latter may befixed to the bracket 86. The paper 204' is at all times properlypositioned with relation to thetypewheel 194 and the hammer-202 by twopairs of cooperating rolltwo open slots 291 and 292 (Fig.2) formed inthe plates 197 and 93 respectively, said slots 0 cm 209, 210, and 2 1 1,212-, (Fig. 8), placed provided for proper .alinement of the ribbon 291and 292 permitting operative positioning and removal of the typewriterribbon 213.

which the calls are started and ended; these means, as will beunderstood, also serve to properly displace the typewriter ribbon 203.Preferably, two small rollers 299 and 300 are 213 within the slots 291and 292 and for cooperation with said ribbon 213'when it is caused to bedisplaced. These rollers may be rotatably mounted on suitable brackets,303 and 303', fixed to or integral with the side brackets 93 and 197respectively.

The width of the hammer 202 and of the paper 204 are such that thehammer 202 successively cooperates with the typewheel 194, as the latteris moved longitudinally along the shaft 32 by the carriage 87, inprinting a record or a telephone number perpendicularly to the edges ofthe paper 204,.as illustrated in F ig: 15, the paper 204 being held 1'stationary when such recording takes place. s5 7 the solenoid mechanism203 (Fig. 9) com- To the inner side of plate 197 ismounted prising asolenoid 216, co-acting with a plunger 217, operating a bell crank219,'pivotedto the post 223. The latter, carries a pivoted arm 220,which cooperates with the hammerl202 through a mechanism which will bepresently described.

Referring to Figs. 2 and 9, a hammer sup porting strip 221 is mountedparallel to the shaft 32.between the plates 93 and 197 and may besecured to the latter. Said strip 221 has two openings for slidinglymounting therein of a pair of pins 222 an 224, fixed tothe hammer 202and to a connec ing member 225, the latter carrying a cap 226 coactingwith the arm 220. The pins 222 and 224 are provided with springs 227 and229, which normally hold thehammer 202.0ut of operative engagement withthe paper ribbon 204:. c

Referring to Fig. 9, a spring 230 has one end connected to a post 231,fixed to the plate 197,- and the other end to a pin, 232,

fixedto the bell-crank 219. The spring 230 cooperates with a post 234also fixed 'to the plate 197 in retaining the mechanism in a normalposition of rest. The pivoted arm 220 is adapted tobe held against thepin 232 by means of a spring 235, which may be connected respectively tosaid arm'220 and to the bell crank 219. 'Thus, an energization of thesolenoid 216 causes the arm 220 to pass, in its travel, in cooperativeengagement with the cap 226, thereby causing a movement of the hammer202 on the paper 204 against the force of the springs 227 and 229.Immediatelyafter passage of the arm the inward movement of the plunger217 and the operative movement of the crank 219.

From the above description, it is clear that both the recording movementand release of the hammer 202 occur during a very'short interval oftime, .sothat the hammer 202, when the solenoid 216 is energized bymeans which will be presently described, may properly record on thepaper 204 at the instant the typewheel 194 reaches the end of itsforward rotary movement, and that the deenergization of the solenoid 216will not cause any recording action of the hammer 202.

Referring particularly to Fig. 3, means for successively energizing andde-energizing the solenoid 216, for successive recording actions of thehammer202, include a spring contact 237, which may be held on the aforesaid insulating block 61. Said spring contact 237 cooperates with theaforesaid spring .contact 59 in establishing and interrupting a circuitthrough the solenoid 216, by reason of the action of the plunger'64 andcap 65 attached thereto, the contact springs 59 and 237 being adapted tobe held normally out [the other terminal of which is connected by a wire240 to the wire 84 leading to the control switches 134 and 135. Acircuit is thus I respectively de-energized and energized, by reason ofthe action of the mutually cooper ating contact spring 59 on'thecon'tact springs 237 and 60..

It is now ,readily seen that, with the springs 59 and 237 normallyspaced, a rotation limiting action of a projection 41 of the element 40with an abutment 42' of a telephone number record 44 causes the plunger64 to substantially simultaneously demag I established andinterruptedthrough the solcnoid 216,- when the clutch 20 is caused to be netiz theclutch and energize the solenoid 216, the hammer 202 then acting torecord the figure corresponding to said rotation limiting action of aprojection 41 with an abutment 42 at substantially the instant therotary movement of the type-wheel 194 is correspondingly arrested. Uponthe reverse'rotation of the element 40, the solenoid 216 is stillenergized but does not cause any recording of figures. Upon the elementbeing restored to its position of rest, the

solenoid 216 is de-energized by reason of the action of the plunger' 64retracting in the tubular portion of the shaft 32, thereby permittingthe movable parts of the mechanism 203 to be restored to their normalposition of rest, without causing any recording of figures by reason ofthe action of the pivoted arm 220, so that said mechanism 203 isreplaced in condition to be again energized to properly record a figurecorresponding to a succeeding rotation limiting action of a projection41with an abutment 42.

Since the rotary movements of the typewheel 194 are exactly proportionalto those of-xthe element 40, the type figures on said wheel 194 may beso positioned that the aforesaid after-employed rotations of the element'40, required to properly transfer a telephone number record in themagazine 171 for storage and limited by the aforesaid projection 132c'o-aeting with an edge 187 and the leg- 17 5 of said telephone numberrecord, do,not cause any recording of figures.

I "magnetization of the clutch, 20, caused by an.

It may be noted that the fillll rotation of the element 40 which islimite ,by the final deopening of the power control switch 135, does notresult in an energizationof the solenoid 216. 1

r In accordance with the invention, means are *provided for recordingthe times at which the receiver hook 4 is actuated to start and end acall, for the purpose of indicating the times at which calls'are madeand the Figs; 1 and 2, typewheels 241, 242 and 244, having formedduration of same.

Referring particularly to on their periphery .figure types indicatinghours, minutes, and seconds, respectively, are

loosely carried by the shaft 32, so as'to be rotatable relatively tosaid shaft. These wheels 241, 242 and 244 are'operatively positionedwith the aforesaid typewhe'el194 within the space between theside-brackets 93 and 197 and extend through the aforesaid opening 201'formed'through the bracket 86. .To the wheels 241, 242 and 244 arefixedly secured, respectively, gears 245, 246 and 247 (see par.-

ticularly Fig. 2). "The latter serve to actuate their respectivetype.wheels by reason of a clock mechanism 249 (Fig. 8-), (not shown indetail), in liason with said gears. The clock mechanism 249 may beconveniently secured to the back surface of the bracket 86,

Referring to Figs. 2 and 8, the time typewheels described areoperatively positioned with relation to the paper ribbon 204, the typewriter ribbon 213 and to a hammer 250 movably mounted on the aforesaidhammer supporting strip 221, the width of said hammally retains thehammer 250 out of cooperative action with the time type-wheels, the

aforesaid pins 251 and 252 preventing arcuate displacement of the hammer250.

Referring to Fig. 8, the aforesaid cap 255 cooperates with a solenoidmechanism 203 which is identicalto the solenoid mechanism 203 alreadydescribed. This mechanism 203 mounted on the inner face of the aforesaiplate 93. -.F or the purpose of brevity, themechanism 203 will not bedescribed, corresponding n u an era 1 s, primed, being employed inconnection, with the mechanism 203 to indicate parts corresponding toidentical parts of the mechanism 203. It maybe well to note that theoperation of the mechanism 203 is similarto thatof the mechanism 203, toeffect instantaneous recording movement and release of the hammer 250.when the solenoid 216-is de-ener gized..

Means ing the solenoid 216 are provided to cause a ,movement ofthehammer' 250 on-the paper 204 when the receiver hoolx 4 iseither raisedor lowered to"startandend a call. Referring to-Fig. 11, these meansinclude a paiv of sprin contacts 257 and 259 which may be mounte onan'i'nsulating'collar 260 fixed to the aforesaid tubular'support 139.The contacts 257 and 259 extend within slots 261 and 262, formed throughsaid support 134, but

do not contact with any part of the' support 134. A contact collar 64is' fixedly held on an insulating portion 265 of the aforesaid rod 136.Said collar 264 travels temporarily for both energizing and de-energizincontact with, but past the inner ends of,

thecontacts 257 and 259, therebytemporarily short-circuiting the same,during either an mer 250 and to prevent actuation of the ham ilThe'springs 257 and 259 slidingly engage the insulating portion 265 of.the rod 136 for any position of the latter except when in contact,withthe collar 264. The springs 257 and 259 may be provided with terminals257 a and 259a for connection thereto of lead-in wires. Referring to thewiring diagram (Fig. 16), one spring contact 257 is electricallyconnected to one side of the switch 189, and the other springcontact'259 is electrical- 1y connected through the solenoid 216' andthe resistance 192 to the other side of the switch 189. From the abovedescription, it is seen that the solenoid 216 is first energized to movethe hammer 250 on the paper 204, and thereafter deenergized as thereceiver solenoid 2,16 is'first energized to move the hammer 250 on thepaper 204, and thereafter deenergized, as the receiver hook 4 is loweredto end a call, the first movement of the hammer 250 being to record thetime at which a call starts and the second movement of such hammerbeingto record. the time at which "such call is completed. The hammer 250, itis noted, is quickin its printing action, it being caused to recedesubstantially instantabers 266 (Fig. 15), are positioned on the paper204 in horizontal alinement with the I recorded times 267 at which thecalls are started; and the recorded times 269 at which ,the calls arecompleted are positioned below the time records 267. Thus, the paper.204 is displaced twice during one operation of the apparatus describedto make a call. One displacement is caused to occur after a record 269is made of. the time at which a call is ended, i. e. just before thereceiver hook 4 has been completely moved to end a call, and the otherdisplacement is caused to'occur just after a telephone number has beenrecorded Referring particularly to Fig. 10, the shaft 141hasper'pendicularly fixed thereto a crank 270 to the end of which is'pivotally linked a rod 271. The latter extends through the base 6, isvertically and slidingly mounted in a tubular support 272, fixed to orintegral with the base 6, and may also be slidably disposed in a tubularguide 313, forming I the shaft 141 that a downward movement of I art ofthe bracket 303-"which carries the a resaid roller 300. The aforesaidcranks 140 and 270 (see Fig. 2) are so positioned relatively to the rod136, by reason of a lowering of the receiver hook 4 to end a call,raises the rod 271.

A pawl 274 is resiliently connected to the hook 4 is raised to start acall, and that the Y upper endof the rod 271. Said pawl 274 cooperateswith a ratchet wheel 27 5, fixedly secured to the shaft 276 of theaforesaid roller rollers21-1 and 212 so that theaction of the pawl 274and ratchet 27 5 causes arcuate displacement of both rollers 211 and 212and thus a displacement of the paper 204. In the drawings these meanscomprise springs 277 acting on the ends of the shaft 278 of roller 312,said ends being held in the slots 279 formed in the two brackets 215supporting the rollers 211 and 212. A 1

The apparatus is so designed that durin the movements of the rod 136 andof the ro 271 by reason of a lowering of the receiver hook 4 to end acall, the contact 264 (Fi 11) comesin contact with the springs 25 and259 before the pawl 274 engages the ratchet wheel 275. Thus, thesolenoid 216' operating the time-record-hammer 250 is energized before adisplacement of the paper 204- by the ratchet wheel 275 takes place.This and the? quick action of the hammer 250 makes possible properrecording of the times at which the receiver hook 4 is being lowered toend calls made. Preferably, however, a dash-pot 280-'(Fig. 13) isprovided to slow the moveproper operation of thea paratus described.This dash-pot 280 may he conveniently secured to the base 6, and isoperated-by the movable'plunger'281, pivotally connected to too vi'ng orending a call evidently not impairing the end of a crank 282, fixedlysecured to the shaft 141..

It isnoted that upon. raisingthe receiver book 4 tostart a succeedingcall, the rod 271 is moved to its lowermost position of rest, therebydisengaging the pawl 274 from its cooperating ratchet-wheel 27 5 sothat'the paper 204 may again be displaced when lower-' ingthe'receiverhook 4th end thatcall.

The means for causing displacement of the paper 204 just after'atelephone number has been recorded include a foot 284 (Figs. 1 and 8),'fixedly secured to the arm 111a of the bell crank 111. When the arm111a is .The lower end of thegrod 285'seats against the foot 284 at alltimes, and a pawl 287,

resiliently mounted on the upper end of the,

- automatically transmitted and recorded. A

' rest; This disengages the pawl 287 from i s spring 290, locatedbetween a collar 293 fixed to the rod 285 and the lower end of thesupport 286, acts to restore the rod 285 to its lower-most position ofrest, when the,

bell crank 111 has been restored to its lowermost position of rest bythe final reverse rotatipn of the element 40 to its position of coactingratchet wheel 289 andproperly positions it for again displacing thepaper204 after a succeeding telephone number has been transmitted andrecorded.

From the above description it is readily seenthat the paper 204 isalready operatively positioned for proper recording thereon beforethereceiver hook 4 is raised to start a call. When a call is made,'atime record is made of the time at which said receiver hook is raised;the telephone number is then transmitted and simultaneously recorded inalinement with said starting time; record; the paper 204 isthendisplaced, before thedriv ing power of the apparatus is interrupted;

and the lowering of the receiver hook to end the call causes both, arecord to be made, below the starting time record, of the. time at whichthe receiver hook is lowered, and also a displacement of the paper 204to properly position it for recording thereon when the succeeding callis made.

Referring to Fig. 1, means for displacing the typewriter ribbon 203include a bevel gear 301 fixed to the outer end of the roller shaft 276.A'second bevel gear 302, meshing with the bevel gear 301, is fixed to avertical shaft 304 rotatably mounted at its upper end in a bearingsupport 305 fixed to or intewas , 306, and the actions of the rods 271and 285,

gral with the bracket'86. 'The aha- 304 is also rotatably mounted at itslower end in a bearing support 314, which forms part of the aforesaidsupporting bracket 303'. A gear 305 is fixedly secured to the shaft 304and meshes with a gear306 fixedly secured to the take-up reel 296. IThus, the take-up reel 296 is movable with the roller 211- by mears ofthe train of gears 301, 302, 305 and producing displacements of thepaper 204 also produce simultaneous displacements of the typewriterribbon 213.
